(-12)+(-13)+36+(-11)

= -12 - 13 + 36 - 11

= - (11+12+13) + 36

= - 36 + 36

= 0

= -25 + 25

= 0 nha 

chuc ban hc tot

(-12)+(-13)+36+(-11)

=-25+36+(-11)

=11+(-11)

=0

\(\left(-12\right)+\left(-13\right)+36+\left(-11\right)=\left[-12+\left(-13\right)+\left(-11\right)\right]+36\)

                                                                         \(=-36+36\)

                                                                         \(=0\)

(-12) + (-13) + 36 (-11) = [ -12 + ( -13 ) + ( -11 ) ] + 36

                                     = -36 + 36

                                     = 0      

0 đúng là 100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000%%%%%

a, 13 + 105 - ( 18 - 8 ) 

 = 13 + 105 - 10 

 = 118 - 10

 = 108

b, ( 64 + 36 +115 ) - 200

  = ( 100 + 115 ) - 200

 = 215 - 200

 = 15

Bài 1:

a)13+21.5-(198:11-8)

= 13+105-(10-8)

= 118-10

= 108.

b)(64+115+36)-25.8

= (100+115)-200

= 215-200

= 15.

Bài 2 :

a)75.8.15.3

= (75.15).8.3

= 1125.8.3

= 9000.3

= 27000.

b)15.6.4.125.8

= (15.6.4).(125.8)

= 360.1000

= 360000.

c)6+8+10+12+14+16+18

= (6+8+10)+(12+18)+(14+16)

= 24+30+30

= 84.

a)75.8.15.3

=(75.8).(15.3)

=600.45

=27000

b)15.6.4.125.8

=(15.6.4).(125.8)

=360.1000

=360000

c)6+8+10+12+14+16+18

=(6+14)+(8+12)+(10+16+18)

=20+20+44

=40+44

=84

36/11 x 22/17 x 51/72

= 36 x 22 x 51/11 x 17 x 72

= 36 x 2 x 11 x 17 x 3/11 x 17 x 36 x 2

= 3

22/16 x 64/55 x 27/13

= 22 x 64 x 27/16 x 55 x 13

=2 x 11 x 16 x 4 x 27/16 x 5 x 11 x 13

= 216/65

36 x 48/12 x 24 + 18 x 104/36 x 4

= 12 x 3 x 2 x 24/12 x 24 + 18 x 13 x 2 x 4/ 18 x 2 x 4

= 6 + 13

= 19

bn đó làm sai bài cuối cũng dc k à

Tính nhanh:

  \(\frac{11}{24}-\frac{5}{41}\)\(+\frac{13}{24}+0,5-\)\(\frac{36}{41}\)

\(=\left(\frac{11}{24}+\frac{13}{24}\right)\)\(-\left(\frac{5}{41}+\frac{36}{41}\right)\)\(+0,5\)

\(=1-1+0,5\)

\(=0,5\)

\(\frac{11}{24}-\frac{5}{41}+\frac{13}{24}+0,5-\frac{36}{41}\)

\(=\left(\frac{11}{24}+\frac{13}{24}\right)-\left(\frac{5}{41}+\frac{36}{41}\right)+0,5\)

\(=1-1+0,5\)
\(=0+0,5\)
\(=0,5\)
Chúc bạn học tốt.

😁😁😁

\(\frac{11}{24}-\frac{5}{41}+\frac{13}{24}+0,5-\frac{36}{41}\)

\(=\)\(\left(\frac{11}{24}+\frac{13}{24}\right)-\left(\frac{5}{41}+\frac{36}{41}\right)+0,5\)

\(=\)\(1-1+0,5\)

\(=\)\(0+0,5\)

\(=\)\(0,5\)

Ta có :

(-12)+(-13)+36+(-11)

=(-13)+36+(-12)+(-11)

=23+(-23)

=0

  -12+(-13)+36+(-11)

=-12-13+36-11

=-25+36

=11-11

=0

(-12) + (-13) + 36 + (-11)

= [(-12) + (-13) + (-11)] + 36

= (-36) + 36

= 0

Chúc bạn học tốt
